M5Stack Scale Kit with Weight Unit

With this kit from M5Stack, you can build a precise DIY IoT digital scale. The kit includes 4 individual weight sensors that can be connected to an HX711 Weight Unit. The unit can then be connected to an M5Stack Core module using the HY2.0-4P connector. The scale has a tolerance of ±0.3%FS and a maximum capacity of 200Kg.
